The impulsive Special Forces agent Sonya Blade knew nothing of other realms until she stumbled upon the Mortal Kombat tournament while pursuing the Black Dragon clan member Kano. After meeting Liu Kang and Raiden on Shang Tsung's island, her purpose in life was forever changed. She convinced her partner, Jax, to help spearhead a division of the Special Forces dedicated to protecting Earthrealm from outside forces. Though she has defended against exotic threats from other worlds, nothing could have prepared her for the invasion to come.
During the world-merge crisis, a member of the Green Lantern Corps was killed. At the moment of his death, his power ring traveled to Sonya, taking her as its new master. When the worlds were once again separated, the ring stayed with her. Now she has the ultimate weapon, but only one charge. She must use the ring sparingly until she can find a way to replenish its power.
